Lintian tag: gir-missing-typelib-dependency

Type: warning

Description (from lintian-explain-tags)

Development packages that contain GObject-Introspection XML files
(/usr/share/gir-1.0/Foo-23.gir or
/usr/lib/${DEB_HOST_MULTIARCH}/gir-1.0/Foo-23.gir) must depend on the
package containing the corresponding binary typelib, which should normally
be named gir1.2-foo-23. The dependency must be strictly versioned (for
example gir1.2-foo-23 (= ${binary:Version}) when using debhelper).

The recommended way to populate the Depends fields is to use debhelper and
dh_girepository, via the gir addon or the dh-sequence-gir virtual package,
and add Depends: ${gir:Depends} to packages that contain GIR XML.

If multiple typelibs are shipped in the same package, then that package
should have versioned Provides for the names that would have been used for
separate packages. In this case, Lintian does not emit this tag when a
group of binary packages from the same source is checked together. Since
gobject-introspection 1.78.1-6 (Debian trixie), the recommended way to
populate the Provides fields is to use debhelper and dh_girepository, via
the gir addon or the dh-sequence-gir virtual package, and add Provides:
${gir:Provides} to packages that contain more than one typelib.

For example, libgtk-3-dev contains Gtk-3.0.gir, Gdk-3.0.gir and
GdkX11-3.0.gir. gir1.2-gtk-3.0 contains all three corresponding typelibs,
so it is sufficient for libgtk-3-dev to depend on gir1.2-gtk-3.0. Giving
gir1.2-gtk-3.0 Provides entries for gir1.2-gdk-3.0 (= ${binary:Version})
and gir1.2-gdkx11-3.0 (= ${binary:Version}) signals this situation to
Lintian.
